Honestly this thread is waaaaayy too hilarious.
The "joke" rests on the general theory that there are, as someone put it "shrill, humourless, agenda-driven flakes" out there who are so steeped in their own culture of victimhood that they cannot let any perceived slight pass without making a federal case out of it.
This thread goes a long way to confirming the well-founded assumption of that joke. Geez - they have a whole lexicon that has to be explained for ordinary people to understand, and their own wiki dictionary.
Thank goodness cooler heads have chimed in to counter-balance the whining and not leave the impression that hiring a Perl programmer will mean having your discussions and meetings completely derailed by socio-political zealotry.
